DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In order to improve a quality of a displaying picture of a displaydevice, an array substrate and a display device according to embodimentsof the present disclosure are provided. According to the technicalsolution of the present disclosure, as the data lines each drives thesub-pixels of the same color, displaying errors caused by differentcorresponding relationship curves between the data output signals andthe pixel grey levels for the sub-pixels of different colors that existin the prior art are avoided, thereby improving quality of a displayingpicture of a display device including the array substrate.

Technical solutions of the present disclosure will be describedexplicitly and fully hereinafter in detail by the way of embodimentswith reference to figures of the attached drawings. Obviously, thedescribed embodiments are only parts of embodiments of the presentdisclosure, rather than all the embodiments. Other embodiments obtainedwithout involving inventive labors by those skilled in the art based onthe described embodiments of the present disclosure fall into the scopeof the present disclosure.

As shown in FIG. 1, there is provided an array substrate according to anexemplary embodiment of the present disclosure, the array substratecomprising:

a plurality of pixel units 100 arranged in an array, each of the pixelunits 100 comprising two sub-pixels of different colors and sub-pixelsin every two adjacent pixel units 100 being arranged in ACBC-type array;and

a set of data lines 10 configured to output data signals to sub-pixelsof the plurality of pixel units 100, each of the data lines 10 drivingthe sub-pixels of the same color.

The array substrate is not limited to any specific type, and may be athin film transistor array substrate or an organic light-emitting diodearray substrate. The embodiments of the present disclosure are describedby taking an organic light-emitting diode array substrate as an example.In a structure of the array substrate, data lines are located below theorganic light-emitting diode and pixel electrodes of the organiclight-emitting diode are coupled to the date lines via a through-holestructure. In an ACBC-type array substrate, in case that a pixelresolution is of 2m×2n (in which m and n are natural number), each pixelunit 100 includes two sub-pixels of different colors and sub-pixels oftwo adjacent pixel units 100 in the same row are arranged in anACBC-type array while sub-pixels of two adjacent pixel units 100 in thesame column are arranged in an ACBC-type array. A, B and C represent oneof red, green and blue, respectively.

For one frame of picture, the signal outputted by the data drive moduleis a matrix, of which matrix elements are drive voltages correspondingto the sub-pixel grey levels. For the existing ACBC-type arraysubstrate, the data signal outputted to sub-pixels of the 2m×2n pixelunits is as below:

wherein m and n are natural number.

Meanwhile, the data signal outputted from the data line by whichsub-pixel A and sub-pixel B are driven is (A₁ ^(q) B₂ ^(q) . . .A_(2m−1) ^(q) B_(2m) ^(q)), wherein 1<q<2n. Since correspondingrelationship curves between the output data signals and the pixel greylevels are not identical for the sub-pixels of different colors,synchronous drive of the sub-pixels of two or more colors by the samedata line in prior art causes displaying errors, thereby degradingquality of the displaying picture.

In the ACBC-type array substrate according to an exemplary embodiment ofthe present disclosure, in case that the array substrate has a pixelresolution of 2m×2n and a set of data lines includes 4n+2 data lines,data signals outputted by the 4n+2 data lines to sub-pixels of the 2m×2npixel units are respectively as below:

$\begin{matrix}\begin{pmatrix}\begin{matrix}0 & 0 & A_{1}^{1} & C_{1}^{1} & B_{1}^{2} & C_{1}^{2} \\B_{2}^{1} & C_{2}^{1} & A_{2}^{2} & C_{2}^{2} & B_{2}^{3} & C_{2}^{3}\end{matrix} & \ldots & \begin{matrix}B_{1}^{{2n} - 2} & C_{1}^{{2n} - 2} & A_{1}^{{2n} - 1} & C_{1}^{{2n} - 1} & B_{1}^{2n} & C_{1}^{2n} \\B_{2}^{{2n} - 1} & C_{2}^{{2n} - 1} & A_{2}^{2n} & C_{2}^{2n} & 0 & 0\end{matrix} \\\vdots & \ddots & \vdots \\\begin{matrix}0 & 0 & A_{{2m} - 1}^{1} & C_{{2m} - 1}^{1} & B_{{2m} - 1}^{2} & C_{{2m} - 1}^{2} \\B_{2m}^{1} & C_{2m}^{1} & A_{2m}^{2} & {C_{2m}^{2}\;} & B_{2m}^{3} & C_{2m}^{3}\end{matrix} & \ldots & \begin{matrix}A_{{2m} - 1}^{{2n} - 2} & C_{{2m} - 1}^{{2n} - 2} & A_{{2m} - 1}^{{2n} - 1} & C_{{2m} - 1}^{{2n} - 1} & B_{{2m} - 1}^{2n} & C_{{2m} - 1}^{2n} \\B_{2m}^{{2n} - 1} & C_{2m}^{{2n} - 1} & A_{2m}^{2n} & C_{2m}^{2n} & 0 & 0\end{matrix}\end{pmatrix} & ( {{equation}\mspace{14mu} 2} )\end{matrix}$

Wherein, m and n are natural number.

In this way, each data line drives sub-pixels of the same color and eachof the sub-pixels may be driven. The data lines in this embodiment atthe same position corresponding to those of the prior art outputs datasignals of (A₁ ^(q) A₂ ^(q+1) A₃ ^(q) A₄ ^(q+1) . . . A_(2m−2) ^(q+1)A_(2m−2) ^(q+1) A_(2m−1) ^(q) A_(2m) ^(q+1)). In order to ensure allsub-pixels in the foregoing two columns and the last two columns to bedriven normally, a first data line outputs a data signal of(0 B₂ ¹ 0 B₄¹ . . . 0 B_(2m−2) ¹ 0 B_(2m) ¹), a second data line outputs a datasignal of (0 C₂ ¹ 0 C₄ ¹ . . . 0 C_(2m−2) ¹ 0 C_(2m) ¹), a last but onedata line outputs a data signal of (B₁ ^(2n) 0 B₃ ^(2n) 0 . . . B_(2m−3)^(2n) 0 B_(2m−1) ^(2n) 0), and a last data line outputs a data signal of(C₁ ^(2n) 0 C₃ ^(2n) 0 . . . C_(2m−3) ^(2n) 0 C_(2m−1) ^(2n) 0). Theforgoing two data lines and the last two data lines output 0 grey levelsfor the sub-pixels that may be driven normally. Compared with theequation 1 in prior art, equation 2 has two 0 grey levels to be insertedin head ends of odd-numbered rows and two 0 grey levels to be insertedin terminal ends of even-numbered rows.

It is noted that, in the abovementioned data signals outputted by the4n+2 data lines to the sub-pixels of the 2m×2n pixel units, A, B and Cmay represent one of red, green and blue, respectively. In other words,A may be red, green or blue.

Manner of the arrangement of the sub-pixel of the plurality of pixelunits 100 in the array substrate is not limited to this. For example, asshown in FIG. 2, a length side and a width side of the pixel unit 100are respectively paralleled to the data line 10 and the gate line (whichis not shown in FIG. 2). As shown in FIG. 3 where the array substrate isan organic light-emitting diode array substrate, sub-pixels of theplurality of pixel units 100 of the organic light-emitting diode arraysubstrate are preferably arranged obliquely and the sub-pixels in thesame oblique line direction are of the same color. In this way, layoutof the array substrate is optimized, and the sub-pixels of the samecolor are arranged in the same oblique line direction such that apattern of a mask plate may be fabricated to be a strip-shape (which isa point-shape in prior art), thereby greatly simplifying manufactureprocess of a light-emitting diode array substrate and reducing cost ofproducing a mask plate. In FIG. 3, the oblique angle of the sub-pixelsis 45 degree, which further optimizes the layout of the array substrate.

FIG. 4 illustrates an array substrate according to another embodiment ofthe present disclosure. The array substrate is a Delta-type arraysubstrate and includes:

a plurality of pixel units 100 arranged in an array, each of the pixelunits comprising three triangularly-arranged sub-pixels of differentcolors; and

a set of data lines 10 configured to output data signals to sub-pixelsof the plurality of pixel units 100, each of the data lines driving thesub-pixels of the same color.

The type of the Delta-type array substrate as shown in FIG. 4 is notlimited to this and may be, such as, a thin film transistor arraysubstrate or an organic light-emitting diode array substrate.

In the Delta-type array substrate, in case that the array substrate hasa pixel resolution of m×n (in which m and n are natural number), each ofthe pixel units 100 includes three triangularly-arranged sub-pixels ofdifferent colors, i.e., a red sub-pixel, a green sub-pixel and a bluesub-pixel.

In a Delta-type array substrate in prior art, a data signal outputted tothe sub-pixel of the m×n pixel units is as follow:

$\begin{matrix}\begin{pmatrix}\begin{matrix}R_{1}^{1} & G_{1}^{1} & B_{1}^{1} \\B_{2}^{1} & G_{2}^{1} & R_{2}^{1} \\R_{3}^{1} & G_{3}^{1} & B_{3}^{1}\end{matrix} & \ldots & \begin{matrix}R_{1}^{n} & G_{1}^{n} & B_{1}^{n} \\B_{2}^{n} & G_{2}^{n} & R_{2}^{n} \\R_{3}^{n} & G_{3}^{n} & B_{3}^{n}\end{matrix} \\\vdots & \ddots & \vdots \\\begin{matrix}B_{m - 2}^{1} & G_{m - 2}^{1} & R_{m - 2}^{1} \\R_{m - 1}^{1} & G_{m - 1}^{1} & R_{m - 1}^{1} \\B_{m}^{1} & G_{m}^{1} & R_{m}^{1}\end{matrix} & \ldots & \begin{matrix}B_{m - 2}^{n} & G_{m - 2}^{n} & R_{m - 2}^{n} \\R_{m - 1}^{n} & G_{m - 1}^{n} & R_{m - 1}^{n} \\B_{m}^{n} & G_{m}^{n} & R_{m}^{n}\end{matrix}\end{pmatrix} & ( {{equation}\mspace{14mu} 3} )\end{matrix}$

wherein m and n are natural number.

The data signal outputted from the data line that synchronously drivesred sub-pixel and blue sub-pixel is (R₁ ^(p) B₂ ^(p) . . . R_(m−1) ^(p)B_(m) ^(p)), wherein 1<q<n. Since corresponding relationship curvesbetween the output data signals and the pixel grey levels are notidentical for the sub-pixels of different colors, synchronous drive ofthe sub-pixels of two or more colors by the same data line in prior artcauses displaying errors, thereby degrading quality of the displayingpicture.

In the Delta-type array substrate according to an exemplary embodimentof the present disclosure, in case that the array substrate has a pixelresolution of m×n and the set of data lines includes 3n+1 data lines,data signals outputted by the 3n+1 data lines to sub-pixels of the m×npixel units are respectively as below:

$\begin{matrix}\; & ( {{equation}\mspace{14mu} 4} ) \\( \begin{matrix}\begin{matrix}R_{1}^{1} & G_{1}^{1} & B_{1}^{1} & R_{1}^{2} & G_{1}^{2} & B_{1}^{2} & R_{1}^{3} \\0 & G_{2}^{1} & B_{2}^{1} & R_{2}^{1} & G_{2}^{2} & B_{2}^{2} & R_{2}^{2} \\R_{3}^{1} & G_{3}^{1} & B_{3}^{1} & R_{3}^{2} & G_{3}^{2} & B_{3}^{2} & R_{3}^{3}\end{matrix} & \ldots & \begin{matrix}R_{1}^{n - 1} & G_{1}^{n - 1} & B_{1}^{n - 1} & R_{1}^{n} & G_{1}^{n} & B_{1}^{n} & 0 \\R_{2}^{n - 2} & G_{2}^{n - 1} & B_{2}^{n - 1} & R_{2}^{n - 1} & G_{2}^{n} & B_{2}^{n} & R_{2}^{n} \\R_{3}^{n - 1} & G_{3}^{n - 1} & B_{3}^{n - 1} & R_{3}^{n} & G_{3}^{n} & B_{3}^{n} & 0\end{matrix} \\\vdots & \ddots & \vdots \\\begin{matrix}0 & G_{m - 2}^{1} & B_{m - 2}^{1} & R_{m - 2}^{1} & G_{m - 2}^{2} & B_{m - 2}^{2} & R_{m - 2}^{3} \\R_{m - 1}^{1} & G_{m - 1}^{1} & B_{m - 1}^{1} & R_{m - 1}^{1} & G_{m - 1}^{2} & B_{m - 1}^{2} & R_{m - 1}^{3} \\0 & G_{m}^{1} & B_{m}^{1} & R_{m}^{2} & G_{m}^{2} & B_{m}^{2} & R_{m}^{3}\end{matrix} & \ldots & \begin{matrix}R_{m - 2}^{n - 2} & G_{m - 2}^{n - 1} & B_{m - 2}^{n - 1} & R_{m - 2}^{n - 1} & G_{m - 2}^{n} & B_{m - 2}^{n} & R_{m - 2}^{n} \\R_{m - 1}^{n - 1} & G_{m - 1}^{n - 1} & B_{m - 1}^{n - 1} & R_{m - 1}^{n} & G_{m - 1}^{n} & B_{m - 1}^{n} & 0 \\R_{m}^{n - 2} & G_{m}^{n - 1} & B_{m}^{n - 1} & R_{m}^{n - 1} & G_{m}^{n} & B_{m}^{n} & R_{m}^{n}\end{matrix}\end{matrix} ) & \;\end{matrix}$

wherein m and n are natural number.

In this way, the data lines each drives sub-pixels of the same color andeach of the sub-pixels may be driven. In order to ensure all sub-pixelsin the foregoing column and the last column to be driven normally, afirst data line outputs a data signal of (R₁ ¹ 0 R₃ ¹ . . . 0 R_(m−1) ¹0) and a last data line outputs a data signal of (0 R₂ ^(n) 0 . . .R:_(m−2) ^(n) 0 R_(m) ^(n)). The forgoing data line and the last dataline output 0 grey levels for the sub-pixels that may be drivennormally. Compared with equation 3 in prior art, equation 4 has one 0grey level to be inserted in head ends of odd-numbered rows and one 0grey level to be inserted in terminal ends of even-numbered rows.

It is noted that, in the abovementioned description, R, G and Brespectively represent red sub-pixel, green sub-pixel and bluesub-pixel. However, the abovementioned equation 4 is not limited torespectively represent the red sub-pixel, the green sub-pixel and theblue sub-pixel by R, G and B. Instead of, R may represent one of thegreen sub-pixel and the blue sub-pixel, G may represent one of the redsub-pixel and the blue sub-pixel and B may represent one of the redsub-pixel and the green sub-pixel, in accordance with actual arrangementof the sub-pixels, in order to achieve a Delta-type array arrangement.
